Abstract

The invention provides a multi-sliding block ranking hot nozzle structure injection mold. The multi-sliding block ranking hot nozzle structure injection mold comprises a mold runner assembly, a mold fixed mold assembly, a mold movable mold assembly, a mold ejection and reset assembly pack, a mold first sliding block mechanism, a mold second sliding block mechanism and a mold third sliding block mechanism. A one-mold two-hole manner is adopted by the mold, a hot runner through nozzle immersed glue input manner is adopted, the mold is parted and opened twice, and automatic injection molding production of the mold is achieved. The mold is simple in structure, and core pulling demolding of the rear mold side face of the product can be reliably achieved. After the product is left on a rear mold, due to the fact that a hot runner is adopted for inputting glue, the appearance quality of the product is greatly guaranteed, and generated waste and use of rear mold ejector blocks are effectivelyreduced. It is guaranteed that the appearance of the injection molding product has no trace, and through overall comparison, the mold is simple and reasonable in structure, the injection molding period is effectively shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to an injection mold with a multi-slider arrangement hot nozzle structure. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Since the product appearance requires side core pulling and demoulding, the injection molding process produces too much nozzle material, and the ejector pin cannot be lowered inside the mold, which affects the product appearance. Contents of the invention [0004] The technical problem to be solved by the pre...
